This book is a Missiological research done as a study on Peaceful coexistence between Christians and Muslims in Nigeria. This book identified that as God's children, we must be committed to the task of living in peace and harmony, and loving our neighbors as ourselves. Round table peaceful dialogue with people of other faith is imperative, because we have been redeemed to pursue peace as we make disciples, baptizing them in the name of the Father, Son, and the Holy Spirit. Therefore, we must understand the relationship between Christians and Muslims. Christians and Muslims in Nigeria must not shy away from peacefully coexisting with each other. This book is a result of my research as a Missiology student who was concerned about the recurrent violent religious attacks and killing of Christians in Southern Kaduna, the Plateau and small Christian villages by radical Islamist (Boko Haram) and Fulani herdsmen, have eluded the peace of these various communities. Living in peace is a necessity, and must be pursued with every sense of urgency. Peaceful coexistence will help us not only build one another but build up our nation as we do God's mission of peacemaking.
